PRIOR ART [0001]The present invention relates to a component for connection to a second component according to the preamble of the independent claim. [0002]A multi-pole multi-row plug-in connector with a screening, intended for being mounted on printed boards or the like, has been described in Utility Patent DE 20 2005 020 474 U1, where the mounting sections of the electric contact elements, which project from the connector housing and which are intended to establish contact with a printed board, and the contact section of the screening are arranged according to a predefined grid pattern and are prepared for being connected to the printed board by soldering. The screening elements comprise contact pins that are passed through holes in the printed board during assembly and are then fixed by soldering. The flat contact elements, having a rectangular conductor cross-section, are bent off at their rear ends facing the printed board by an angle of approximately 90 degrees in order to provide a sufficiently large contact area for being soldered to the printed conductors on the printed board. [0003]DE 10 2004 037 786 A1 describes a printed board with SMD devices to be mounted, where at least one component comprises a connection wire that is pushed through a metallized connection bore in the printed board during assembly of the printed board. The printed board is provided for assembly of components on both sides. In order to ensure that the component to be mounted, provided with the connection wire, will not fall off the connection bore when the printed board is turned over it is provided to fill at least part of the connection bore with a conductive bonding agent prior to the mounting operation. After assembly of the SMD device the conductive bonding agent then encloses the connection wire of the SMD device over the full area of the connection bore, thereby fixing the connection wire in its position before it is soldered. The connection bore is made up from at least two bores that interact one with the other so that a portion of reduced cross-section is obtained in the connection bore in an overlapping area of the bores. That reduced cross-section is intended on the one hand to fix the connection wire of the SMD device in the bore prior to the soldering operation, while its main function is to assist in establishing the electric contact with the connection wire. The printed board can be described as the first component, intended to be connected with the conductive bonding agent, which latter can be described as the second component. [0004]Patent Application DE 102 19 427 A1 describes a method for producing a mechanical and an electric connection between a printed board and a contact pin to be arranged on the printed board. The contact pin is hollow, on at least one of its ends, and provided with an external bead near the hollow end. In a first step, a paste solder is applied around a receiving passage opening provided in the printed board for the contact pin. Thereafter, the contact pin is positioned on the printed board so that the hollow end of the contact pin comes to extend into the receiving passage opening and to project beyond the other side of the printed board when its external bead abuts against the one side of the board. A conical expanding device is heated up for the purpose of expanding the hollow end of the contact pin. The hollow end of the contact pin is then expanded by means of the heated-up expanding device and is fused by the heat conducted from the expanding device through the contact pin to the external bead. [0005]Patent Application DE 35 36 494 A1 describes a method of producing a milling cutter where a tool carrier is fitted with two cutting edges of the milling cutter. Production of the tool carrier by investment casting is carried out simultaneously with the permanent mechanical connection of the tool carrier. The cutting edges are provided with openings with enlargements in cross-section that are to be filled by the liquid metal of the tool carrier being produced. Once the molten material has solidified, the tool carrier so produced is already positively connected with the cutting edges. [0006]Now, it is the object of the present invention to provide a first component, intended for being connected with a second component, which allows a mechanically stable connection to be achieved by extremely simple means and which, when provided, allows an electric connection with good electric properties to be obtained. [0007]That object is achieved by the features defined in the independent claim. DISCLOSURE OF THE INVENTION [0008]The component according to the invention, intended for being connected to a second component, comprises at least one recess with at least one opening which will be filled at least in part by the second component which latter is in a flowing condition during establishment of the connection, at least in the area of the opening. The recess in the first component comprises a reduction in cross-section that will be back-filled by the second component during establishment of the connection. The reduction in cross-section is provided in the recess on the side facing the second component. The component according to the invention allows connection to be established with a second component that may have metallic properties or may be made from a plastic material. It is merely necessary that the second component be in flowing condition during establishment of the connection, at least in the region of the opening, so that the second component can penetrate into the recess in the first component and can back-fill the reduction in cross-section facing the second component. [0009]The first component should be sufficiently thermostable, at least in the region of the opening, to ensure that the second component, which normally will have been heated up in the process of rendering the material flowable, cannot cause the first component to melt. [0010]A mechanically stable connection between the first and the second components is achieved by the fact that due to the arrangement of the reduction in cross-section in the recess on the side facing the second component an increased lever arm is obtained that counteracts any tilting or torsional movements between the two components. [0011]When the first component is an electric component that is to be fixed on a board by soldering, where the second component is preferably constituted by the soldering material, a substantial advantage results from the fact that the opening need not be filled up completely by the soldering material. This results in considerable cost advantages especially in series production. [0012]Additional cost advantages result especially from the fact that no further measures are required to guarantee a durable connection between the first component and the second component. Especially, no components such as screws or clamps are needed. [0013]Advantageous further developments and embodiments of a first component according to the invention are apparent from the dependent claims. [0014]An advantageous feature provides that the at least one recess comprises at least one further opening provided for example on the side facing away from the second component. The further opening may act as pressure-relief and prevents air from being trapped. [0015]The first component preferably consists of a connection element of an electric and/or electronic component. The electric and/or electronic component may especially be an SMD device (surface-mount device). Particular advantages are achieved when the first component is a plug-in connector. Using the feature provided according to the invention, an especially stable connection is achieved between the plug-in connector and the printed board, combined with low consumption of soldering material, the latter constituting the second component in that case. The first component may in this case consist of a contact element, a screening element or a connection element of the plug-in connector. [0016]Further, the second component provided may especially be a plastic part that is to be positively connected with the first component. The plastic material, being liquid or at least in a flowing condition when the connection is made, at least in the area of the reduction in cross-section in the recess of the first component, penetrates into the recess at least in part, but preferably into the entire recess, thereby establishing an undetachable connection with the first component. [0017]According to an advantageous embodiment, a plurality of recesses, each comprising one reduction in cross-section, may be provided in the first component. It is possible in this way to produce load-carrying connections between the two components. [0018]A simple way of producing the recess with its reduction in cross-section consists of providing two bores with different bore diameters. [0019]According to an alternative, the reduction in cross-section is formed using an expanding device. Suited as expanding device is a conical die, for example. The expanding device used for forming the reduction in cross-section may be used also in cases where the first component is made from metal. [0020]According to a further alternative, the reduction in cross-section is produced by giving the recess a dovetail shape at least in the area of the reduction in cross-section. This permits the first component, including the recess with the reduction in cross-section, to be produced by a single operation. [0021]Certain embodiments of the invention are illustrated in the drawing and will be described hereafter in more detail.
